Wright WPA 3.5's What's Next?

I am the owner of these amps and was wondering if anyone has owned these and moved on to better things?Can anyone suggest an amp that they have preferred over these mono's for their efficient(Horn speakers 103db)system.Not looking to break the bank either i should add.I was going passive using the EVS nude attenuator and recently switched to the Eastern Electric Minimax active preamp.Am i barking up the wrong tree in thinking about moving on from these amps?i think i am trying to gain a bit more lushness PERHAPS.My system does sound really nice but was wondering just what might be the next step for me guys?My system is posted but i haven't added the Minimax to the list yet as i was still auditioning it and i think it is a keeper over going passive.
thanks!!
